Steam radiator made of copper pipe?
I have an old house that uses steam heat and has big, single-pipe, cast-iron steam radiators. I wanted to replace one of them with something modern looking, and one company sells such radiators, but they are very expensive (sold here http://steamradiators.com/)
My question is, can I make one of these out of large (1.5" or so) diameter copper pipes, soldered together in the same fashion? I've read that steam systems typically operate at 1psi of pressure, which sounds like it's well below the safety limit of copper pipes and solder joints.
I think it would look fantastic, but would it work?
